The Sun Hydraulics COKAXZN (COKAXZN) is a high-performance, pilot-to-close check cartridge valve designed for hydraulic applications requiring reliable control of fluid flow. This valve operates by allowing flow from port 1 to port 2 while blocking reverse flow, ensuring operational efficiency and safety in systems where such unidirectional flow is critical. It features a nominal pilot ratio of 1.8:1, meaning that a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1. This characteristic makes it particularly suitable for use in regeneration circuits. Constructed to fit into Sun's T19A cavity at reduced capacity, the COKAXZN achieves its full capacity when installed in the T19AU cavity. With a maximum operating pressure of 5000 psi and a maximum flow rate of 240 gpm, this valve is capable of handling substantial hydraulic loads. The design incorporates Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations in the cavity/cartridge. The COKAXZN also features corrosion-resistant options (indicated by model code suffixes AP or LH), enhancing its durability and suitability for corrosive environments. It ensures minimal leakage with a rating of less than one drop per minute at 110 SUS viscosity, and requires an installation torque between 350 and 375 lbf ft. Weighing in at approximately 2.60 lb, this robust valve combines high performance with reliability, making it an essential component for advanced hydraulic systems demanding precise fluid control.

This valve is a spring biased closed, pilot-to-close check cartridge that has a 1.8:1 pilot ratio. The valve allows flow from port 1 to port 2 and blocks reverse flow. Pressure at the pilot port opposes pressure at port 1 at a ratio of 1.8:1. This valve is most often used in regeneration circuits.
- These valves will work in Sun's standard T-19A cavity at lower capacity. To realize the full stated capacity, the T-19AU cavity should be used.
- Nominal pilot ratio is 1.8:1. This means that a pressure of 1000 psi (70 bar) at the pilot port will close a valve against a pressure of 1800 psi (125 bar) at port 1. Any decay or loss of pilot pressure could allow the valve to open, even if it is a momentary decay or loss.
- Pressure at the port 2 area directly opposes pilot pressure.
- Reverse flow through the valve from port 2 to port 1 is not possible under any condition.
- With equal pressures at all ports the valve is closed.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP or /LH (see CONFIGURATION section). For further details, please see the Materials of Construction page under TECHNICAL RESOURCES.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
